LID-SUPPORTING DEVICE.

Application filed September 10, 1919.

To all whom it may concern:

Be it known that I, STUART W. l ansoNs, a citizen of the Unlted States, residing at New Britain, in the county of Hartford,

State of Connecticut, have invented certain new and useful Improvements in Lid-Supporting Devices, of which the following is a specification.

This invention relates to devices for sup porting in raised position hinged parts, such as covers or lids of articles of furniture, boxes and the like and it has particular reference to supporting devices of the type wherein a prop-bar pivotally secured to the hinged cover or lid cooperates with a stationary bracket in such manner that when the cover is raised the prop-bar will be automatically brought to a seat in the bracket to maintain the cover in raised position and then when the cover is further raised the prop-bar is automatically withdrawn from said seat and moved into a position where the hinged cover may be lowered.

It is the object of the present invention to provide an improved bracket for guidmg and supporting the prop-bar of a lid supporting device, which bracket 1s efficient 1n operation, simple in constructlon, strong and durable and which may be readily and" that it is not limited to this specific use, and

Fig. 2 is a bottom view of my improved bracket.

Referring to the drawings in detail, 10 designates a cabinet of a talking machine having, is usual, a hinged cover 11 and a platform 12 provided with an elongated slot. Pivotally secured at its upper end to the hinged cover 11 is a prop-bar 13 having, adjacent its lower end, a projection or stud 14.

My improved bracket comprises a top plate 15 overlying th slot in the platform 12 and having an elongated slot 15 through which the prop-bar 13 extends, and a guide plate 16 extending downwardly from one edge of the plate 15 and having a passageway through which the projection 14 of the prop-bar travels when the cover 11 is raised and lowered. The top plate 15 may be se- Specification of Letters Patent.

cured to the platform in any suitable manner, as by means of indicated screws 17.

The guide plate 16 is preferably integral with the top plate 15, the entire bracket being by preference formed by stamping and pressing a single piece of sheet metal into proper form and shape. The guide plate 16 has a pair of ribs 18 and 19 leading up wardly from the lower edge of the guide plate and between these ribs is a rib or bridge 24, the upper edge of which is V- shaped to form the lower edge of a V-shaped slot 20, the upper edge of this slot being defined by the projection 25. The ribs 18 and 19 provide channels which together with the slot 20 form a passageway or guideway of ubstantially EVE-shape for the projection 1%. Leading upwardly and rearwardly from the top of the channel in the rib 18 to the slot 20 is a slot 26 and these two slots form a slot similar in shape to a horizontally disposed capital Z. The depression in the up per edge of the bridge 24 forms a seat 21 into which the projection 14 of the prop bar is automatically brought when the hinged cover 11 is raised into open position, as is clearly shown by dotted lines in Fig. 1. The forward wall of the bridge or rib 24 is in clined so as to form a cam surface 22 along which the projection or stud 14: of the prop bar rides when the cover is raised. The wall or cam surface 22 and the rear wall 27 of the rib 24 are such parts as respond to what is described in some of the claims as angularly disposed or opposite facing walls.

When the cover 11 is raised, the lower end of the prop-bar 13 swings forwardly or away from the hinged end of the cover until it is in vertical position; the stud 1 1 then moves upwardly into the channel of the rib 18 and rides up the inclined wall 22 into the forward end of the Z-shaped slot, further upward movement of the cover being limited when the projection 14 has moved into engagement with the edge 23 defining the top of the slot; the cover is allowed to fall slightly and thereupon due to gravity, the lower end of the prop-bar swings rearwardly toward the hinged end of the cover and the projection 1 1 is automatically brought to rest in the seat 21, as shown by the dotted lines in Fig. 1. When it is desired to close down the cover, the cover is raised in a direction to further open the same, whereupon the projection 14 of the quantities at a relatively low cost.

prop-bar travels up the rear end of the V- I shaped slot 20 until it is brought into registry with the channel in the rib 19 and then the cover may be lowered, the projection of course passing downwardly through the channel in the rib 19.

Brackets constructed in accordance with the present invention may be formed by merely stamping from a sheet of metal a blank conforming to the shape of the top plate 15 and the guide plate 16 and having I the slot 20 in the guide plate; pressing out the ribs 18 and 19 in the guide plate, and then bending the top plate over at right angles to the guide plate. It will be seen that my improved bracket requires but very few and comparatively inexpensive and simple operations in its manufacture, all maon the edges of the Z-shaped slot in the plate, are exerted in the plane of the guide plate. It will further be noted that the bracket hereindescribed may be readily and quickly applied to a talking machine cabinet or other receptacle, it being merely necessary, in installing the device, to insert the guide plate into the elongated slot in the platform 12 and then drive the screws 17 into place. The screws are in such position that they may be readily inserted, it being entirely unnecessary to gain access to the interior of the cabinet beneath the platform or insert any fastening means in any corner or place not readily accessible.

Itis of course obvious that my invention is susceptible of various modifications and changes which are within the spiritof the invention without departing from the scope ofthe followin'g'claims, it being understood that the present disclosure of my invention is by way of illustration only and it is not to be taken as restrictive ofmy conception.
